Using PVC pipe for dryer vents is not recommended due to its inability to withstand the high temperatures emitted by the dryer. Over time, the heat can cause the PVC to soften and potentially release harmful fumes, posing a fire hazard and a health risk through the emission of toxic gases. Building codes in many areas specifically prohibit the use of PVC for this purpose. Instead, it's advisable to use materials that are designed for high temperatures, such as rigid metal ducts or flexible metal tubing. These alternatives provide a safer option that meets the building codes and reduces the risk of fire and health hazards associated with the use of PVC in high-temperature situations.

Connecting PVC pipe to an elbow involves a few specific steps, ensuring a watertight fit for plumbing or other piping applications. Firstly, measure and cut your PVC pipe to the required length, using a saw for a clean cut. Next, deburr the cut edge to remove any roughness, enhancing the adhesive's effectiveness. Clean both the pipe end and the inside of the elbow fitting with a PVC primer, which prepares the surfaces by softening the PVC. Once the primer has dried (following the manufacturer's instructions for drying time), apply a liberal coat of PVC cement to both the outside of the pipe and the inside of the elbow. Quickly insert the pipe into the elbow, twisting slightly to distribute the cement evenly and hold in place for a few seconds to ensure the bond begins to set. It is crucial to ensure proper alignment during this step as the cement sets quickly. Finally, allow the connection to cure for the recommended time before subjecting it to pressure. Wear safety equipment like gloves and ensure adequate ventilation during this process.
